Re: Retaining Wall Questions

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I the 5' - 0" setback is usually recommended in your area pay a soils engineer for a letter that state this.
To me that seems to be not enough.....what if you have a wet year and half or all the soil is gone in front of the wall......the wall may go bye - bye and so does your license.....especially if the client knows a lawyer or is one.   Today you are responsible for your clients gross stupidity according to a lot of court decisions. Sooo  be cautious with what people ask for.
So it is good if not prudent to err on the side of conservatism

Question: In a stacking, stepped retaining wall situation, if and when is it reasonable to disregard the sliding force from the upper wall on the lower wall? 

Need more informationDo you have to key the upper wall ??
